SPECIFICATION forming part of Letters latent No. 414,412, dated November 5, 1889.

Application filed April 26, 1889. Serial No. 303,690. (No modeh) To (all wi'mI/t- 17mg concern-.-

Be it known that I, WILLIAM S. IIERRING- T03, of San Francisco, in the county of San Francisco and State of California, have invented a new and Improved Miter-Box, of which the following is a full, clear, and exact description. I

The object of the invention is to provide a new and improved miter-box which is simple and durable in construction, very eifective in operation, quickly taken apart for convenience in carrying or packing, and adjustble to admit any-sized stick, molding, or board to'be operated on.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the improvement. Fig. 2 is an end elevation of the same. Fig. 3 is an enlarged elevation of one of the rollerframes, and Fig. 4 is an enlarged plan view of the notched segment.

The improved miter-boXAis provided with a bottom board B, on one edge of which is secured at right angles a board G, provided with a vertically-extending V-shaped notch D, the sides of which are at right an gles to each other. Directly below the board O, on the under side of the board B,is held the base E of a segment E by means of a bolt F, also passing through a bar G and screwing into the bottom board B. The bar G ext-ends transversely across the bottom 13 and under the segment E, as is plainly shown in the drawings.

In order to hold the segment E in place on the board 13, I provide it with ofiset-s E fitting against the edge of the board B, thus holding the segment conveniently in place. The bolt F is centrally below the inner edge of the vertical board O-that is, in line with the apex of the vertically-extending notch D. On top of the segment E are arranged a number of notches E formed at suitable angles, indicating the miter to be out.

On the bar G are held to slide the rollerframes II and H, of which the roller-frame II is in front of the board C, while the other is in the rear of the same. Each roller-frame II and II is provided near its lower end with an aperture I through which passes the bar G, and each roller-frame is adapted tobe secured in place on the bar G by a set-screw I, screwing in the bottom of the respective roller-frame and against the bar G. In each roller-frame II or H are held to turn the rollers J and J, extending parallel and vertically, as shown in Fig. Each roller J J is preferably covered with a flexible materialsuch as rubber-and the lower ends of the rollers are mounted to turn on the studs K, secured in the roller-frames. The upper end of each roller J J is held to turn on the lower reduced end of a screw L, screwing in the top of the roller-frames. W'hcn the screws L are screwed outward, the rollers J and J can easily be detached from their respective rollerframes, in order to be repaired whenever necessary.

Near the rear end of the bar G is pivoted a spring-arm N, adapted to pass into one of the notches E in the segment E. A nut N screws on the outer end of the spring-arm N to secure the latter on the segmentE at points where notches are not provided.

The operation is as follows: When the several parts of the miter-box are in place, as illustrated in Figs. 1 and 2, the spaces between the rollers J J of the roller-frames H and H are in line with the apex of the notch D in the board C. IVhen the operator now inserts the saw-blade between the rollers J J of the roller-frames II ll, the saw passes through the apex of the notch D, and when the bar G is held at right angles to the bottom board 15, as shown in the drawings, the stick, molding, or board held on the said bottom board is cut square when the saw is operated. \Vhen the operator now desires to cut a stick, molding, board, or other article at any desired angle, he disengages the springlever N from the central notch E, and then swings the bar G to the right or left, according to the angle desired, or until the springlever N drops into a corresponding notch E in the segment E. The bar G then stands at such an angle as it is desired to cut the article held in the bottom of the miter-box.

It is to be understood that the roller-frames H and H are open at the top, so as to conveniently insert the saw-blade. It will further be understood that the entire miter-box can be easily and conveniently taken apart by simply removing the bolt F from the bottom board B and loosening the set-screws I,

so as to detach the roller-frames H and H from the bar G, that it may be conveniently carried or packed in a tool-chest. It will be further seen that the roller-frames H and H can be moved in or out on the bar G, so as to make room for articles of different diameters. It will also be seen that the roller-frames H and H can be adjusted close up to the sides of the bottom board B, that may be of any desired width, so that considerable stroke can be given to the saw.

Any ordinary saw can be used in this mitor-box, thus doing away with the necessity of keeping a special saw for the miter-box.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In a miter-box, the combination, with the segment E, notched on its upper surface, of the bar G, pivoted to the under side of the base of the segment, the spring-lever N, projecting from the bar G across the notched face of the segment and provided on its outer end With a nut to clamp against the curved edge of the segment, and the saw-guides adjustable on the bar G, substantially as set forth.

2. The combination, with the segment E, having notches E a base E, and abutments E E at the juncture of the ends of the segment with the base, and the bottom board B, secured on the base E, with its inner edge against said abutments and having the Vertical board 0 flush with its inner edge and provided With a vertical V-shaped slot, of the bar G, pivoted at F to the base E, and provided at the outer end of its short arm With a looking device engaging said notches, and the saw-guides adjustable on said bar, substantially as set forth.

3. The combination, With the segment and the arm G pivoted thereto, of the frames H H, having slots H in their lower closed ends and in Wardly-projecting bearin gs at their up per ends, the parallel rollers J J in said frames, and the vertical pivots K L between the ends of the rollers and the bottom of the said frames and said inwardly-extending lugs, substantially as set forth.
